Just a note, but but when I was working on the last type traits update, I
spent a lot of time trying to program the classes using types rather than
values for that very reason, however I could never really get it to work
(which is not to say that I didn't miss something).  That's why I reverted
to values (which IMO are conceptually the right thing to be using anyway),
and wrote a set of guidelines for using them: 
http://www.boost.org/more/int_const_guidelines.htm.  Most of the time, you
can program with values and non-type template parameters with Borland C++
provided you always use ::fully::qualified::names.
